Abstract
A seismic vibration control device for structures which employs a combination of primary and secondary vibratable masses to attenuate the vibration of a structure. The primary vibratable mass is passive and is supported on the structure. One or more active secondary vibratable masses are supported on the primary mass. Control forces are selectively applied to the secondary masses to control the period of the primary mass in a manner which is most effective to attenuate the seismic vibration of the structure.
